Question

How can the observable universe be over 90 billion light-years across when the universe is only 14 billion years old?

Answer 1

“light years” is a measure of distance- the distance light has traveled in a year of movement.
Perhaps the rate of expansion of the universe is faster than the speed of light and has outpaced our age.

Edit: I agree, my original comment made little sense.
